BACKGROUND

Pieces of exercise equipment, such as exercise racks, are generally static, limiting the functionality of the equipment to a small number of exercises. Thus, in order to perform a large variety of exercises, many individual pieces of equipment are often required. However, such arrangements can be costly and can take up excessive space.

SUMMARY

Aspects of the disclosure are generally directed toward exercise racks having a movable purpose bar. Exemplary racks can include a frame having a variety of support elements. The frame can support first and second movable vertical supports that are horizontally movable within the frame (e.g., movable front to back within a rectangular frame). A movable purpose bar can be attached to the first and second movable vertical supports such that the movable purpose bar can be moved vertically along the movable vertical supports. Thus, the movable purpose bar can be moved vertically, along the movable vertical supports, and horizontally, as the movable vertical supports are moved horizontally within the frame. The purpose bar can include an attachment point for receiving one or more of a variety of attachments, which can be used for performing a variety of different exercises. When the attachment(s) are attached to the movable purpose bar, the movement of the purpose bar can facilitate positioning of the attachments for convenient use by a user. This can be useful as a user changes exercises (e.g., from one attachment to another) and/or as different users (e.g., users having different heights) perform a single exercise. Such a versatile, multi-purpose exercise rack can replace several individual pieces of equipment, saving cost and space when compared to acquiring and storing each piece of equipment individually.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of an exemplary purpose rack capable of a variety of configurations and receiving a variety of attachments for facilitating a variety of different functions. In the illustrated example, purpose rack 100 includes a base comprising lower guide bars 102 a and 102 b and a connecting section 104 connecting the lower guide bars 102 a and 102 b. In the example of FIG. 1, the connecting section 104 comprises a C-shaped section connecting the lower guide bars 102 a-b.

Purpose rack 100 of FIG. 1 includes vertical legs 110 a, 110 b, 110 c, and 110 d extending upward from the base. In the illustrated embodiment, vertical legs 110 a-d and lower guide bars 102 a-b are configured such that lower guide bar 102 a extends between vertical legs 110 a and 110 b and lower guide bar 102 b extends between vertical legs 110 c and 110 d. In the embodiment shown in FIG. 1, vertical legs 110 a-d include holes, for example, for receiving one or more leg-connectable accessories, such as barbell supports, safety bars, or the like. In some examples, holes included in the vertical legs 110 a-d are similar to those found in frames of common squat racks. In some embodiments, the spacing between holes in vertical legs 110 a-d is uniform along a length of the vertical legs 110 a-d. In other examples, one or more of vertical legs 110 a-d include a first length having holes spaced apart by a first distance, and a second length having holes spaced apart by a second distance that is different from the first.

In the example of FIG. 1, vertical leg 110 a includes a first length L1 having a plurality of holes spaced apart by a first distance and a second length L2 having a plurality of holes spaced apart by a second distance. Some such vertical legs (e.g., 110 a-d) can include additional lengths separate from the first and second lengths. That is, a first length having holes spaced apart by a first distance and a second length having holes spaced apart by a second distance that is different from the first need not combine to extend the entire length of a leg.

The purpose rack 100 of FIG. 1 includes an upper support 114 a extending between vertical legs 110 a and 110 d and upper support 114 b extending between vertical legs 110 b and 110 c. The exemplary purpose rack 100 further includes upper guide bar 112 a extending between vertical legs 110 a and 110 b and upper guide bar 112 b extending between vertical legs 110 d and 110 c. In some embodiments, upper supports 114 a-b and/or upper guide bars 112 a-b provide structural integrity between vertical legs 110 a-d.

In some embodiments, the combination of the base (e.g., the lower guide bars 102 a-b and connecting section 104), the vertical legs 110 a-d, the upper supports 114 a-b, and the upper guide bars 112 a-b make up a frame of the purpose rack 100. In some embodiments, the frame of the purpose rack 100 comprises components that are generally fixed relative to one another.

In the illustrated example of FIG. 1, upper supports 114 a and 114 b each include an attachment point 116 a and 116 b, respectively. Attachment points 116 a-b can be used to receive one or more accessories, such as those described elsewhere herein, to facilitate multiple uses of the purpose rack 100. While shown as being positioned in both upper supports 114 a-b, attachment point(s) can be positioned in a variety of locations, such as one on or both of upper supports 114 a-b, vertical legs 110 a-d, or any other appropriate location.

In the embodiment of FIG. 1, purpose rack 100 includes movable vertical support 122 a extending between the lower guide bar 102 a and the upper guide bar 112 a and movable vertical support 122 b extending between lower guide bar 102 b and upper guide bar 112 b. In various examples, the cross-sectional shape of movable vertical supports (e.g., 122 a-b) can be any number of shapes. For examples, in various embodiments, the cross-sectional shape of one or more movable vertical supports can be a square, rectangle, rounded rectangle, oval, circle, or any other appropriate shape.

In some embodiments, movable vertical support 122 a is configured to be movable along the upper 112 a and lower 102 a guide bars such that the movable vertical support 122 a can be moved between vertical legs 110 a and 110 b. Similarly, in some embodiments, movable vertical support 122 b is configured to be movable along the upper 112 b and lower 102 b guide bars such that the movable vertical support 122 b can be moved between vertical legs 110 c and 110 d.

In the illustrated embodiment, movable vertical support 122 a includes attachment portions 128 a, 130 a configured to interface with and secure movable vertical support 122 a to lower guide bar 102 a and upper guide bar 112 a, respectively. Similarly, movable vertical support 122 b includes attachment portions 128 b, 130 b configured to interface with and secure movable vertical support 122 b to lower guide bar 102 b and upper guide bar 112 b, respectively.

In some embodiments, attachment portions 128 a-b, 130 a-b facilitate translation of the movable vertical supports 122 a-b along the direction of guide bars 102 a-b, 112 a-b. For instance, in some examples, attachment portions (e.g., 128 a) can include one or more rollers configured to roll along a surface of an associated guide bar (e.g., 102 a). For example, with reference to FIG. 1, attachment potion 130 a includes rollers 132 a, 134 a configured to roll along an upper surface of upper guide bar 112 a. Similarly, attachment potion 130 b includes rollers 132 b, 134 b configured to roll along an upper surface of upper guide bar 112 b. In some embodiments, attachment portions 128 a-b include similar rollers interfacing with an upper surface of lower guide bars 102 a-b. While shown as interfacing with an upper surface of the upper guide bar, rollers can additionally or alternatively interface with other surfaces of such guide bars. Exemplary rollers can include, for example, polymer rollers to enable smooth and quiet motion of the movable vertical support (e.g., 122 a). Other materials are also possible, such as metallic bearings or the like.

In some embodiments, one or more attachment portions (e.g., 128 a-b, 130 a-b) can be locked in place relative to the associated guide bar (e.g., 102 a-b, 112 a-b) via a locking mechanism. Exemplary locking mechanisms can include a pin, such as a lockout pop pin, that can prevent movement of the attachment portion relative to the associated guide bar when engaged, and allow movement of the attachment portion relative to the associated guide bar when disengaged. Additional or alternative locking mechanisms are possible, such as, for example, one or more magnetic elements, one or more indentations in which rollers (e.g., 132-b, 134 a-b) settle to prohibit motion of the movable vertical supports relative to guide bars, one or more positionable surfaces (e.g., brakes) that can selectively apply friction to the rollers to inhibit rolling, one or more stops positionable to selectively prevent motion of the movable vertical supports relative to guide bars, or the like.

The purpose rack 100 further includes a purpose bar 120 supported by movable vertical supports 122 a-b. In the embodiment of FIG. 1, the purpose bar 120 includes end portions 124 a and 124 b for interfacing with movable vertical supports 122 a and 122 b, respectively. In some examples, an end portion (e.g., 124 a) is configured to surround an outer surface of a corresponding movable vertical support (e.g., 122 a). In some such examples, each end portion 124 a-b is shaped to match the cross-sectional shape of the corresponding movable vertical support 122 a-b.

In some examples, the purpose bar 120 can be vertically movable relative to the movable vertical supports 122 a-b. For instance, in some such examples, the end portions 124 a-b of the purpose bar 120 are movable with respect to the movable vertical supports 122 a-b. In some embodiments, the purpose bar 120 can be locked in place relative to the movable vertical supports 122 a-b via one or more releasable attachment mechanisms (e.g., 126 a-b). In the exemplary embodiment of FIG. 1, the one or more releasable attachment mechanisms comprise spring-loaded pins 126 a-b configured to extend through a hole in a respective end portion 124 a-b and enter one of a plurality of holes formed in a surface (e.g., the inner surface) of the respective movable vertical support 122 a-b. For example, in the illustrated embodiment, spring-loaded pin 126 a is configured to extend through a hole in end portion 124 a and into one of a plurality of holes formed in the inner surface of the movable vertical support 122 a, wherein the spring-loaded pin 126 a is spring biased to be retracted into the hole in the movable vertical support 122 a. Similarly, spring-loaded pin 126 b is configured to extend through a hole in end portion 124 b and into one of a plurality of holes formed in the inner surface of the movable vertical support 122 b, wherein the spring-loaded pin 126 b is spring biased to be retracted into the hole in the movable vertical support 122 b.

Thus, in such embodiments, to reposition the purpose bar 120 relative to movable vertical supports 122 a-b, the spring-loaded pins 126 a-b can be pulled out of a hole in each of the movable vertical supports 122 a-b. The purpose bar 120 can then be moved relative to the movable vertical supports 122 a-b, and the spring-loaded pins 126 a-b can be released, causing the spring-loaded pins 126 a-b to retract into different holes in the movable vertical supports 122 a-b. Thus, even if a user accidentally drops the purpose bar 120 while spring-loaded pins 126 a-b are extracted from holes in the movable vertical supports 122 a-b, the spring-loaded pins 126 a-b will spring back into holes to prevent the purpose bar 120 from undesirably falling and potentially injuring the user.

While shown in the illustrate example as being positioned on inner surfaces, in various embodiments, holes in the movable vertical supports 122 a-b can be positioned on any surface of the supports. Holes can be spaced apart by uniform or varying distances, for example, as discussed elsewhere herein with respect to lengths L₁ and L₂ of vertical supports. In some examples, holes can be positioned substantially along the length of the movable vertical supports 122 a-b to increase the range of motion of the purpose bar.

Thus, in some embodiments, the purpose bar 120 is movable in at least two dimensions, for example, relative to the frame of the purpose rack 100. For instance, the movable nature of the attachment portions 128 a-b, 130 a-b relative to the lower 102 a-b and upper 112 a-b guide bars enables front-to-back (and back-to-front) motion of the purpose bar 120 by way of moving the movable vertical supports 122 a-b relative to the lower 102 a-b and upper 112 a-b guide bars. Additionally, the movable nature of the purpose bar 120 relative to the movable vertical supports 122 a-b enables up and down movement of the purpose bar 120 relative to the movable vertical supports 122 a-b.

In some embodiments, the purpose bar 120 includes an attachment point 150. Attachment point 150 can be configured to interface with corresponding attachment points of one or more accessories for cooperative engagement of the accessory and the purpose bar. Such accessories can include one or more pieces of exercise equipment to facilitate different exercises by a user. The ability to position the purpose bar 120, and thus the attachment point 150 for attaching the accessory, facilitates an adjustable position for the accessory attached to the purpose bar 120. Adjusting the position of the accessory can be done to accommodate, for example, for the height of the user and/or the desired actions to be performed by the user using the accessory.

For instance, in an exemplary embodiment, an accessory comprises a pull-down accessory, wherein a user pulls down a grip element (e.g., a bar) against resistance. In using such an accessory, the accessory should be located above the user in order to facilitate the “pull down” motion. However, the desired starting location of the grip element may vary from user to user, for example, depending on the heights of the users. The desired starting location may also vary based on whether the user is seated or standing. Thus, the positioned of the accessory can be adjusted to accommodate the user's desired operation of the accessory by repositioning the purpose bar 120 within the frame of the purpose rack 100.

FIGS. 2-4 illustrate components that can be combined to form a purpose rack such as purpose rack 100 in FIG. 1.

FIG. 2 is a perspective view of a frame 205 for a purpose rack. In the illustrated example, frame 205 includes a base comprising lower guide bars 202 a and 202 b and a connecting section 204 connecting the lower guide bars 202 a and 202 b. In the example of FIG. 2, the connecting section 204 comprises a C-shaped section connecting the lower guide bars 202 a-b.

Frame 205 of FIG. 2 includes vertical legs 210 a, 210 b, 210 c, and 210 d extending upward from the base. In the illustrated embodiment, vertical legs 210 a-d and lower guide bars 202 a-b are configured such that lower guide bar 202 a extends between vertical legs 210 a and 210 b and lower guide bar 202 b extends between vertical legs 210 c and 210 d. In the embodiment shown in FIG. 2, vertical legs 210 a-d include holes, for example, for receiving one or more leg-connectable accessories, such as barbell supports, safety bars, or the like. In some examples, holes included in the vertical legs 210 a-d are similar to those found in frames of common squat racks. In some embodiments, the spacing between holes in vertical legs 210 a-d is uniform along a length of the vertical legs 210 a-d. In other examples, one or more of vertical legs 210 a-d include a first length having holes spaced apart by a first distance, and a second length having holes spaced apart by a second distance that is different from the first.

In the example of FIG. 2, vertical leg 210 a includes a first length L1 having a plurality of holes spaced apart by a first distance and a second length L2 having a plurality of holes spaced apart by a second distance. Some such vertical legs (e.g., 210 a-d) can include additional lengths separate from the first and second lengths. That is, a first length having holes spaced apart by a first distance and a second length having holes spaced apart by a second distance that is different from the first need not combine to extend the entire length of a leg.

The frame 205 of FIG. 2 includes an upper support 214 a extending between vertical legs 210 a and 210 d and upper support 214 b extending between vertical legs 210 b and 210 c. The exemplary frame 205 further includes upper guide bar 212 a extending between vertical legs 210 a and 210 b and upper guide bar 212 b extending between vertical legs 210 d and 210 c. In some embodiments, upper supports 214 a-b and/or upper guide bars 212 a-b provide structural integrity between vertical legs 210 a-d.

In some embodiments, the combination of the base (e.g., the lower guide bars 202 a-b and connecting section 204), the vertical legs 210 a-d, the upper supports 214 a-b, and the upper guide bars 212 a-b make up a frame of the frame 205. In some embodiments, the frame of the frame 205 comprises components that are generally fixed relative to one another.

In the illustrated example of FIG. 2, upper supports 214 a and 214 b each include an attachment point 216 a and 216 b, respectively. Attachment points 216 a-b can be used to receive one or more accessories, such as those described elsewhere herein, to facilitate multiple uses of the frame 205. While shown as being positioned in both upper supports 214 a-b, attachment point(s) can be positioned in a variety of locations, such as one on or both of upper supports 214 a-b, vertical legs 210 a-d, or any other appropriate location.

FIGS. 3A-3C show different views of an exemplary movable vertical support. FIG. 3A shows a front-on view of an exemplary movable vertical support 322. In the illustrated examples, the movable vertical support 322 includes an elongate body 323 extending between an upper attachment portion 330 and a lower attachment portion 328. In some embodiments, the elongate body 323 includes a cross-sectional shape as described elsewhere herein.

The front-on view of the upper attachment portion 330 shows rollers 332 and 336 separated by a gap 335. Gap 335 can be configured to receive, for example, upper guide bar 212 a or 212 b of the frame 205 in FIG. 2 such that roller 332 engages a top surface of the upper guide bar 212 a or 212 b and roller 336 engages a lower surface of the upper guide bar 212 a or 212 b. Similarly, the front-on view of the lower attachment portion 328 shows rollers 340 and 344 separated by a gap 343. Gap 343 can be configured to receive, for example, lower guide bar 202 a or 202 b of the frame 205 in FIG. 2 such that roller 340 engages a top surface of the lower guide bar 202 a or 202 b and roller 344 engages a lower surface of the lower guide bar or 202 b.

The perspective view in FIG. 3C shows roller 334 disposed behind roller 332, and thus obscured from view in the front-on view of FIG. 3A. Similarly, movable vertical support 322 can include a roller (not shown) disposed behind any one or more of rollers 336, 340, and 344. Thus, each attachment portion (328, 330) can include a plurality of rollers as described elsewhere herein to facilitate smooth motion of the attachment portions along guide bars.

As described elsewhere herein, and as shown in the side view of FIG. 3B, the elongate body 323 of the movable vertical support can include one or more holes, which can be configured to receive, for example, a pin for locking various components in place relative to the movable vertical support 322. While shown as disposed along the side of the elongate body 323, such holes can be positioned in any of a variety of locations along the elongate body 323 of the movable vertical support 322. Holes can be evenly spaced along the length of the elongate body, can have variable spacing, or can have separate lengths in having a different hole spacing associated with each length.

FIGS. 4A-4C show different views of an exemplary purpose bar. FIG. 4A is a front-on view of an exemplary purpose bar 420. The purpose bar 420 includes end portions 424 a and 424 b. The end portions 424 a-b can be configured to interface with movable vertical support(s) such as movable vertical support 322 shown in FIGS. 3A-3C. The purpose bar 420 includes releasable attachment members, shown in FIGS. 4A-4C as spring-loaded pins 426 a-b operably coupled to end portions 424 a-b, respectively. As described elsewhere herein, spring-loaded pins 426 a-b can be configured to be spring biased outward, toward end portions 424 a-b. Thus, an inward force can be applied to spring-loaded pins 426 a-b to retract pins 426 a-b inward. Upon release of the force, the pins 426 a-b can spring outward.

FIGS. 4B and 4C show a top-down view and a perspective view, respectively, of the purpose bar of FIG. 4A. The views of FIGS. 4B and 4C show the purpose bar having an attachment point 450, which can be configured to receive corresponding attachment points of one or more accessories as described elsewhere herein. As shown in the illustrated example of FIG. 4B, the end portions 424 a-b include apertures 425 a-b, respectively. In some examples, apertures 425 a-b can be shaped to receive the elongate body (e.g., 323) of a corresponding movable vertical support (e.g., 322). For example, in some embodiments, an aperture (e.g., 425 a) in an end portion (e.g., 424 a) of a purpose bar (e.g., 420) can be shaped the same as or similarly to the cross-sectional shape of a corresponding elongate body (e.g., 323) of a movable vertical support (e.g., 322). In some embodiments, one or both of apertures 425 a-b can include one or more rollers, such as those described elsewhere herein, configured to engage one or more surfaces of the movable vertical support extending through the aperture.

In some examples, the spring-loaded pins 426 a-b extend into apertures 425 a-b, respectively, for example, to engage one of a plurality of holes in the elongate body (e.g., 323) of a movable vertical support (e.g., 322). Thus, by disengaging spring-loaded pins 426 a-b from the movable vertical supports (e.g., by applying sufficient inward force on pins 426 a-b), the spring-loaded pins 426 a-b disengage from the movable vertical supports, facilitating motion of the purpose bar 420 along the movable vertical supports. In some examples, in addition to or alternatively to engaging holes in the elongate body of a movable vertical support, spring loaded pins 426 a-b may frictionally engage an outer surface of the elongate body of the movable vertical support(s) to prevent motion between the purpose bar 420 and the movable vertical support(s).

Thus, with reference to FIGS. 2, 3A-C, and 4A-C, in an exemplary construction of a purpose rack (e.g., purpose rack 100 in FIG. 1), a pair of movable vertical supports such as movable vertical support 322 of FIG. 3 can be inserted into the apertures 425 a-b, respectively, in the purpose bar 420 of FIG. 4. The upper guide bars 212 a-b of frame 205 of FIG. 2 can be inserted into gaps (e.g., 335) between rollers (e.g., 332 and 336) in an upper attachment portion (e.g., 330) in movable vertical supports (e.g. 322). Similarly, the lower guide bars 202 a-b of frame 205 in FIG. 2 can be inserted into gaps (e.g., 343) between rollers (e.g., 340 and 344) in a lower attachment portion (e.g., 328) in movable vertical supports (e.g. 322). The resulting purpose rack includes a frame in which a purpose bar is movable in at least two dimensions (forward and backward due to the motion of the movable vertical supports relative to the frame and vertically due to motion of the purpose bar relative to the movable vertical supports).

FIG. 5 shows a front-on view of an assembled purpose rack. Similar to the embodiment shown in FIG. 1, the purpose rack 500 of FIG. 5 includes a vertical legs 510 a and 510 d comprising a plurality of holes therein to facilitate attachment of a variety of components. An upper support 514 a includes an attachment point 516 further capable of facilitating attachment of components, such as accessories as described herein. A base includes a connecting section 504, for example, connecting lower guide bars (not shown) as described elsewhere herein. A purpose bar 520 is positioned within the purpose rack. Releasable attachment mechanisms (e.g., spring-loaded pins 526 a-b) can facilitate vertical motion of the purpose bar 520 as indicated by arrows 560 and as described elsewhere herein.

FIG. 6 is a top-down view of an assembled purpose rack. Similar to the embodiment shown in FIG. 1, purpose rack 600 includes upper guide bars 612 a-b and upper supports 614 a-b. A base includes a connecting section 604, for example, connecting lower guide bars (not shown) as described elsewhere herein. As shown, the connecting section 604 includes an attachment point 607 that can receive, for example, a portion of an accessory for use with the purpose rack 600. The purpose rack 600 includes a purpose bar 620 which includes releasable attachment mechanisms (e.g., spring-loaded pins 626 a-b), which can facilitate attachment of the purpose bar 620 to the purpose rack 600. As described elsewhere herein, the purpose rack 600 can include movable vertical supports (not shown) that interface with the releasable attachment mechanisms (e.g., spring-loaded pins 626 a-b) to support the purpose bar 620.

In some embodiments, movable vertical supports include attachment portions 630 a and 630 b configured to interface with upper guide bars 612 a and 612 b, respectively, such as described elsewhere herein. In the illustrated example of FIG. 6, attachment portion 630 a includes rollers 632 a and 634 a, and attachment portion 630 b includes rollers 632 b and 634 b. Rollers 632 a, 632 b, 634 a, and 634 b can facilitate motion of the attachment portions 630 a and 630 b along upper guide bars 612 a and 612 b, respectively. As described elsewhere herein, any number of rollers can be used, including rollers hidden from the top-down view of FIG. 6.

In embodiments in which movable vertical supports (not shown) support the purpose bar 620 (e.g., via spring-loaded pins 626 a-b), motion of attachment portions 630 a and 630 b of the movable vertical supports along upper guide bars 612 a and 612 b can facilitate motion of the purpose bar 620 in the directions of arrows 662. Purpose bar 620 includes an attachment point 650 for receiving one or more attachments as described elsewhere herein. Movement of the purpose bar 620 in the directions of arrows 662 corresponds to repositioning of the attachment point 650. This enables a user to move the attachment point to an appropriate location for use of the accessory attached to the purpose bar 620 as described elsewhere herein. In some examples, purpose bar 620 can be configured so attachment point 650 is movable along the length of the purpose bar 620, for example in the directions of arrows 664.

FIG. 7 is a side view of an assembled purpose rack. Similar to the embodiment shown in FIG. 1, purpose rack 700 includes lower guide bar 702 b, upper guide bar 712 b, vertical legs 710 c and 710 d, and a base includes a connecting section 704, for example, connecting lower guide bar 702 to another lower guide bar (not shown) as described elsewhere herein. The illustrated embodiment of FIG. 7 shows a movable vertical support 722 b. The movable vertical support 722 b includes a lower attachment portion 728 b interfacing with the lower guide bar 702 b. In some examples, lower attachment portion 728 b interfaces with lower guide bar 702 b to facilitate motion of the lower attachment portion 728 b along the length of the lower guide bar 702 b, for example, in the direction of arrows 762. Similarly, the movable vertical support 722 b includes an upper attachment portion 730 b interfacing with the upper guide bar 712 b. In some examples, upper attachment portion 730 b interfaces with upper guide bar 712 b to facilitate motion of the upper attachment portion 730 b along the length of the upper guide bar 712 b, for example, in the direction of arrows 762.

As shown, the movable vertical support 722 b interfaces with an end portion 724 b, for example, of a purpose bar (not shown). As described elsewhere herein, the end portion 724 b can be movable along the length of the movable vertical support 722 b in the direction of arrows 760. Thus, a purpose bar (not shown) supported by movable vertical support 722 b via end portion 724 b can be moved in at least two dimensions, in the directions of arrows 760 and arrows 762.

Thus, as described with respect to FIGS. 5-7, in various embodiments, an attachment point on a purpose bar can be moved in up to three dimensions relative to the frame of the purpose rack. For example, the attachment point can be moved back and forth within the purpose rack (e.g., along directions of arrows 662 and 762 in FIGS. 6 and 7, respectively), up and down within the purpose rack (e.g., along directions of arrows 560 and 760 in FIGS. 5 and 7, respectively), and side to side, for example, along the length of the purpose bar (e.g., along directions of arrows 664 in FIG. 6). In various embodiments, movement may be possible in any one of such dimensions, any two of such dimensions, or all three dimensions.

The adjustable position of the attachment point relative, for example, to the frame of the purpose rack, can be useful for positioning the attachment point for use with a particular accessory. For example, during exemplary operation, a user may position attachment point to a first position and attach a first accessory to the attachment point, wherein the first accessory is configured for facilitating a first exercise. After the user has completed the first exercise, the user may remove the first attachment, reposition the attachment point to a second position, and attach a second accessory to the attachment point, wherein the second accessory is configured for facilitating a second exercise. In general, a user can adjust the position of the attachment point to optimize the position of an attachment for the size and/or functionality of the equipment and/or the size of the user. Additionally or alternatively, certain attachments may include a recommended purpose bar position with which to use the attachment. For instance, in some cases, the attachment may be used by users of all sizes without repositioning of the entire attachment. Rather, in some such examples, portions of the attachment itself can be adjusted to better fit the user. Thus, in some such examples, the purpose bar may be moved to a recommended position for use with the particular attachment.

In some examples, various accessories for attaching to the purpose rack (e.g., via the attachment point on the purpose bar) include an attachment portion that is configured to attach to an attachment point on the purpose bar. FIGS. 8A-8C show various views of an exemplary attachment portion for one or more accessories. FIG. 8A is a perspective view of an exemplary attachment portion, FIG. 8B is a front view of an exemplary attachment portion, and FIG. 8C is a side view of an exemplary attachment portion. As shown, attachment portion 870 of FIG. 8A includes a housing 872 having a front wall 874, a top wall 876, and a back wall 878, and a post 880 extending into a channel formed by the front wall 874, top wall 876, and back wall 878. In some embodiments, to the post 880 is configured to engage with the attachment point (e.g., 450) of the attachment bar, while the attachment bar itself extends through the channel formed by the front 874, top 876, and back 878 walls. In some embodiments, the channel is approximately the same height and/or approximately the same width as the purpose bar.

In some embodiments, the attachment portion 870 includes a locking mechanism for removably securing the attachment portion 870 to a purpose bar. For example, in the illustrated example, post 880 includes a hole 882, for example, for receiving a locking pin. The housing 872 can include one or more openings, such as openings 884 and 888 in the front 874 and back 878 walls, respectively, facilitating access to the hole 882 in the post 880. For instance, in an exemplary embodiment, to attach the attachment portion 870 to a purpose bar, a user inserts post 880 into an aperture located at the attachment point of the purpose bar. Once the post 880 is inserted fully into the purpose bar (e.g., and top wall 876 engages a top surface of the purpose bar), hole 882 may be exposed, for example, below the purpose bar or in a corresponding hole in the purpose bar. A locking pin or other object can be inserted into the hole 882 in the post 880 to lock the attachment portion 870 to the purpose bar.

In some examples, the housing 872 of the attachment portion 870 can facilitate the attaching of the attachment portion 870 to various attachments for use with the system, such as via screws or other fasteners. However, it will be appreciated that in some examples, attachment mechanisms need not include each or any of the housing surfaces (e.g., 874, 876, 878). For example, in some embodiments, an attachment portion can include a post such as 880 attached directly to an accessory, for example, via a welded joint.

Attachment portions (e.g., 870) can be included on one or more accessories to facilitate attachment of the accessory to the purpose rack. In some examples, such attachment portions can be used to attach to an attachment point on a purpose bar. Additionally or alternatively, attachment portions can be used to attach to one or more other attachment points in the purpose rack, such as holes in the vertical legs (e.g., 110 a-d), attachment points (e.g., 116 a-b) in upper supports (e.g., 114 a-b), attachment point 607 in the base (e.g., connecting section 604) or other attachment location in the purpose rack.

In some embodiments, one or more attachment points (e.g., holes in vertical legs 110 a-d, attachment point 607 in base, etc.) can be used to secure a purpose bench within or otherwise proximate the purpose rack. The purpose bench can be used in conjunction with different attachments to facilitate various exercises using such attachments. In some examples, the purpose bench is attached in a prescribed way to the purpose rack and operates in conjunction with an attachment attached to the purpose bar. In some such examples, the purpose bar can be moved to a recommended location for use with both the particular attachment and the purpose bench. Additionally or alternatively, a purpose bench need not physically attach to the purpose rack to be used in conjunction with such attachments.
